Today I finally used my membership to Tyler Arboretum in Media Pa.
elevation 378'

http://www.tylerarboretum.org/ Tyler is one of the oldest and largest arboreta in the northeastern United States, encompassing 650 acres of horticultural collections, rare specimens, ancient trees, historic buildings, and extensive hiking trails. The Arboretum offers a wide variety of workshops, classes, and tours for both adults and children, as well as school groups, scout groups, and clubs. As a private, not-for-profit organization, Tyler is not government supported. The Arboretum survives and thrives on the support of our members and donors. Please browse our site, then plan a visit to this unique and beautiful destination, where we connect neighbors with nature.

Tyler Arboretum was originally the land of Thomas Minshall, an English Quaker. The land was granted to him by William Penn in 1681. The property was handed down through several generations of the Minshall, Painter, and Tyler families. In 1944 the property was bequeathed to the public as an Arboretum. A few trees remain from the original grant date, one is the state co-champion tulip poplar at 420 points. About 20 trees remain from the Painter brothers 1825 collection. Cedar of Lebanon, Oriental Spruce, Bald Cypress, and Giant Sequoia are four that are recognized by the State champion tree program.

Today I followed Rocky Run from the Main house down into the woods to where it intersects with Dismal Run, which in turn enters into Ridley creek. I was surrounded with spring ephemerals! Mayapple, blood root, trout lily, cut leaved tooth wort, false solomons seal, spring beauty, and skunk cabbage among others.

I was surprised at the amount of trout lily flowers, as I was told they bloom on a seven year cycle. I have never seen as many flowers as I saw today. The ferns were sprouting to the point that it looked like someone buried a thousand violins. Maple leaf viburnum shared the understory with Spicebush, witch hazel, and Arrowwood viburnum. Hornbeam, Hophornbeam, red maple, and smaller hardwoods were next. The canopy consisted of Red, White, Chestnut, Scarlet and Black oak. Pignut, Bitternut, Shagbark, shellbark, and Mockernut Hickories. Tulip poplar, beech, white ash, Black Walnut and mazzard cherry. I didn't see any birch. Rocky run is just that.

It slowly winds down through an open, wide draw, exposing all sizes of dark grey, rounded boulders and some quartz. The sides of the draw are not steep, and it is easy to walk straight up. Here is what I found for girth and heights:

Tulip poplar            137.0 x 11.1
Tulip poplar            141.5 x 13.4
Shagbark                126.1 x 6.5
Shellbark                110.2 x 5.7
Shellbark                126.1 x 5.5
White ash               120.6 x 7.6
Red oak                  114.9 x 8
Bitternut                126.8 x 8.2
Black oak                129.5 x 9.9
Beech                    116.9 x 11.2
White oak               115.5 x 8
Pignut                    113.3 x 6

Rucker for ten species is 123.1

141' by 13' Tulip Poplar



I only spent about 4 hours in the draw, and I think some of these can be beat. Very skinny trees for the height. There were MANY more trees that were over 12'CBH, but had little height.

Other native trees in the garden were:

Bald cypress                107.6 x 12.8
River birch                   70.2 x 10.3
Vernal Witch Hazel        27.9 x 1.25
Scarlet oak(?)               118.8 x 14.6 (may be red oak)
Giant Sequoia               95.4 x 12.9
White pine                   91.0 x 11.8

I will find out about the scarlet/red oak, as once it is identified, it will change the rucker. It is just outside the garden area in the woods. If it is a red oak, the rucker would be 123.5. If it is a scarlet, the rucker would be 124.0.

Scott,

Nice find Scott. I had no idea that there were still 650 acres of
undeveloped land left in the Media area. Leave it to the Quakers to have
the good sense and foresight to preserve such a great place. I really have
to get back down there one of these days to see some of these amazing places
you find down there. When I was living there 16 years ago, I obviously
wasn't paying enough attention.

That 126.1' shagbark hickory blows the 118.4' one I found right out of the
water. The other hickories are really something and so is the black oak.

Not only is Tyler big, but Ridley creek state park adjoins Tyler with another 2600+ acres. Alot of it is overrun with invasives, but There are rumors of big trees in there. I will get in there someday! Once you get into Chester county above route three, there is alot of old money farms. The Willistown township conservancy has put alot of it into trust.
